Method Detail

create

public Resource create(ResourceManager frontEnd, ResourceData data, ResourceKey context, Class[] target)

createKey

public ResourceKey createKey(Object data, Map parameters)

deriveKey

public ResourceKey deriveKey(ResourceKey parent, String path, Map parameters)

Derives a new key from the given resource-key. Only keys for a hierarchical storage system (like file-systems or URLs) can have derived keys. Since LibLoader 0.3.0 only hierarchical keys can be derived. For that, the deriving path must be given as String.

The optional parameter-map will be applied to the derived key after the parent's parameters have been copied to the new key.

Before trying to derive the key, the system tries to interpret the path as absolute key-value.

Parameters: parent the parent key, or null to interpret the path as absolute key. path the relative path, that is used to derive the key. parameters a optional map containing resource-key parameters.

Returns: the derived key.

Throws: ResourceKeyCreationException if deriving the key failed.

Parameters: key the resource-key.

Returns: the resourceloader for that key, or null, if no resource-loader is able to process the key.

Throws: ResourceLoadingException if an error occured.
